FAUCET.

Specification of Letters Patent No. 22,402, dated December 21, 1858.

To all whom it may concern:

Be it known that We, MARTIN Romains and JAMES POWELL, both ofCincinnati, Hamilton county, Ohio, have invented certain new and usefulImprovements in Faucets; and We hereby declare the following to be afull and exact description of the same, reerence being had to theaccompanying drawings, making part of this specification, and in Which-aFigures 1 and 2 are respectively a vertical and a horizontal axialsection and Fig 3 a diagram illustrating the action of the conipensatingcollar hereinafter explained.

This invention relates to that class of cocks in which a valve and seattake the place of the more customary taper chamber and perforated plug',and consists in an arrangement to insure the eiiective relative Workingof the valve and the key, and to prevent leakage around the stein of thelatter.

A, represents the barrel or chamber, B the neck, C the nozzle, D thevalve seat, E the valve (of india rubber or like substance), F the capand G the socket of customary form.

L is the valve stem connected at its front end with a yoke M having therepresented trefoil aperture and on its under side a floor N perforatedwith an oblong slotn to permit the traverse of the valve stein and atthe same time prevent its lateral deviation from a right line. The underside of the yoke M, rests upon the elevated rim of the socket G.

The bit I-I of the key H I J K has on one side a projection 7i, which asthe key is turned operates the valve through the medium of the yoke M.

7:/ is a fiange surmounting the projection 7L and engaging above thevalve stem L so as to conne it to a horizontal path. The rectilinearmotion of the valve stem is "further insured by guide pins O, which arees-4 pecially useful in steadying the valve to its seat.

rEhe severe horizontal pressure of the valve stein upon the key in thisclass of cocks tending to Wear the pin and socket oval, the ordinarycollar is found insuicient to close the joint around the key stem, afterit has been for a time in use. To remedy this defeet We have placed thecollar I low down, and over it a Washer P and annular cushion Q, ofindia rubber or other suitable material which supports a loose collar Rso as to cause it to fit snugly up to the under side of the cap althoughthe key may be deliected. F 3 exhibits the action of this cushionedcollar.

IVe claim as new and of our invention herein- The application to the keystein of the collar I, cushion Q and loose collar It, or theirequivalents, arranged and operating in combination in the mannerdescribed to conipensate for the lateral Wear or displacement of thesaid stem.

In testimony of Which invention we hereunto set our hands.
